Commits

Commit	What was done	Why it was done	Details
b625b41	chore: update rpm spec to Apache-2.0 and verify tarball hash	Initial implementation of the Apache-2.0 license change and a naive tarball hash check.	Details Files: scripts/package/build-rpm-package.sh Validation: bash -n Risk/rollback: Low
8bc8c5a	fix: actually verify the tarball sha256 against its checksum file	The naive check merely computed the hash; this commit strictly compares it against an expected checksum file using sha256sum -c.	Details Files: scripts/package/build-rpm-package.sh Validation: bash -n Risk/rollback: Low

Validacao

• Ran bash -n scripts/package/build-rpm-package.sh to confirm syntax integrity.
• Verified changes using git diff.

Rollback trigger

Revert if RPM package builds consistently fail due to incorrect or missing .sha256 checksum files in the source path.
